I tend to have a whole lot of female NPCs with power, but I also include some off the quasi-sexist fantasy staple characters on occasion.
If anytinhg, touhgh, women in traditional roles that are not fantasy archetype ones tend to be more than meets the eye. They in many ways drive the politicla intrigue far more than the men do.
In my game world, human cultures are genrally civilized enough to have gender equality, with that sort of prejudice being reserved for "inferior" species like humanoids. There is one nation basically ruled by women, called Dasheban (basically a rip off of FR's Rasheman), but the society itself is rather equal other than the fact that it is controlled by a group of female spellcasters who derive their power from a genetic ability tha tdoes not manefest in men.
Sample Female NPCs: (My players don't read. This can spoil the whole campagn).

Lady Brianna Wagner: A debutante, politician and owner of a large company that manufactures and sells magical items, she is also the masked and very powerful adveturer who seems to be attacking prominent citizens and officials by night (all of which she has discovered to be evil/corrupt, but no one knows that yet). The name Brianna Wagner quite intentionnally sounds a bit like Bruce Wayne.
Silara Stormlord: The Paladin of Tyranny/Stormlord who is the archenemy of the PC paladin. She is completely heartless and cruel, doesnt talk much, and rides a black unicorn (which flies thanks to her PRC abilities). She basically fits the traditionally-male archetype of the Black Knight/Evil Champion.
Rachel Zarun: Seemingly the dutiful wife to the lord of the city the PC are based in, she turned out to be a demon of pure energy whom the PCs trapped within a sword. Before her fall, she used her position in the court and her unusual powers to assassinate her husband's political rival and frame the rivals wife, and tried to kill another one too, although her accidentally killing a simulacrum instead wound up blowing her cover.
Lady Seaflame, Tarsha, and Kayla: Agents sent from Dasheban to infiltrate the court and keep an eye on Rachel Zarun, who'se identity they were aware of. Seaflame was a powerful witch and prominent politician who gained the PC's trust and convinced them that R.Z. was evil. Her daughters, Kalya and Tarsha, wound up as personal attendants to R.Z. Seaflame was killed by a bounty hunter and Tarsha (a witch) died in the battle that resulted in R.Z. getting trapped in the sword. Kayla is a dervish who now works with the PCs, and is sort of the stereotypical powerful but fragile female warrior who nonetheless fits the bratty little sister archetype, needs saving more often than the guys, and sometimes will flirt to get what she wants.
Queen Alina of Dasheban: Galadriel archetype. Personally the most powerful leader of any nation. However, at a summit, the people gathered there, including the PCs, supported letting her guard the Staff of Creation, an uber-artifact of unknown origion. Eventually, they will discover that this was about as bad as giving Galadriel the One Ring would have been.
Clarissa Zarun: A current main BBEG, although the PCs havent figured it out yet., she is a child vampire lord loosely based on Claudia from Anne Rice's Interview with a Vampire. Her father was a mighty necromancer who treated her like a slave and eventually turned her undead in an experiement in his search for the ultimate undead from. Of coruse, since it wasnt a feature he needed, he did nothing to mature her, and she is trapped in the body of a child -- and with certain childlike tendancies -- forever. Out of revenge and a quest for a new body, she altered his final preparations, turning him into a hideous, non=spellcasting monster which she eventually unleashed on a city to be killed.
She was responsable for setting a circle of demons free, joining up with them, and at the same time ensuring that the PCs found the swords meant to recapture them after they had reeked enough havok and taken enough control.
She worships the imprisoned crocodile god Sobek, and she plans to use the captured spirits of the demons to free him, and with the help of Alina, corrupted by the Staff of Creation, plans on taking them from the PCs to achieve that end and to seize control of their minions.
The demons have offered to create her a new body of demonflesh; one which is beautiful and powerful and free of the immaturities that remain in her mind, and thus she is posing as the daughter of the lord of the PCs home city, who is also the lead demon (the PCs suspect this, and have begun to work with Alina against him...they do not, however, suspect Alina). However, she knows that only the Staff of Creation, which only Sobek, its creator, can properly weild, can make her a body that fulfills her expectations, so she plans on betraying her master as well once the time is ripe.
